[Known] Incorrect rim lighting on many game objects/characters

Many objects, including characters, have rim lighting that is out of place. Attached an image with some examples.

Note the lighting on the player's helmet, player's cloak, crates, skull w/ candle, etc in the image below. There is no light source in the room (and there is certainly no light source behind these objects that might cause such rim lighting), and it is night, so the lighting effects are rather strange.

Another good example where it is dark outside. Notice the strange rim lighting around objects and characters, particularly around the bird statue. Also, notice the odd purple lighting effect even though there is no purple moon above.
